Discard any excess liquid so the purée doesn’t become watery.
Transfer the thawed mango to a blender or use an immersion blender.
Blend until completely smooth.
Press the purée through a fine-mesh sieve to remove fibers and achieve a silky texture.
Weigh out 320 g smooth mango purée for the recipe.
Pre-heat the oven to 180 °C and grease a 18 cm round cake pan.

Chill the cake in the fridge for a minimum of 6 hours to set
Decoration
Once cake fully sets refrigerated, open the mousse ring and proceed with decoration
